I have two tables artist and arts. artistId is a primary key in artist table and it is the foreign key in arts table.I am using stored procedure to insert data. first artist log in and then art info page is displayed where artist insert art info.I want that artist id to get inserted in arts table also when he inserts art info.I tried this as:
stored procedure:
if exists(select artistId from artist)
insert into arts(name,description,artistId) values(@name,@description,@artistId)

asp.net code:

SQL

cmd.Parameters.AddWithValue("@name",txtname.Text);
        cmd.Parameters.AddWithValue("@category",ddlcategory.SelectedValue);

It is not working.
I am new to stored procedure.Please help me to get the foreign key value.Or is there any other way?

What do you mean by "not working" - please be specific

Member 10724668 28-Apr-14 11:00am

it is giving error as artistId can not be null

Solution 1

you have 3 parameters in your stored procedure, need to set all the parameter values.
when artist login to system you can get the artistId from the database and keep that value.

C#

cmd.Parameters.AddWithValue("@name",txtname.Text);
cmd.Parameters.AddWithValue("@category",ddlcategory.SelectedValue);
cmd.Parameters.AddWithValue("@artistId",artistId);

It is giving error as the name artistId does not exist in the current context

that's why I added "when artist login to system you can get the artistId from the database and keep that value"
